14 smart_molding international 4/2022 newsfeed With the additively manufactured HASCO Streamrunner®, a new age has begun in the world of hot runner tech - nology. Developed with state-of-the- art technologies, this product creates new possibilities for mouldmakers and injection moulders. Design freedom in new dimensions The Streamrunner® is an additively manufactured hot runner with maxi - mum design freedom. With this tech - nology the flow channels can be op- timally designed in rheological terms by completely avoiding sharp edges and areas with poor throughflow properties. This gentle passage of the melt leads to considerably lower shear rates and consequently to bet- ter quality of the injection-moulded parts. Colour changes can also be carried out faster through the flow-optimised design be- cause the material can be guided via large deflec- tion radii. Multi-component injection moulding at a new level Through the free three-dimensional design of the runners, completely new possibilities are also created in multi- component injection moulding. Differ- ent plastic components or colours can be spread over a very small space and the runners can be intertwined. This allows product designers to overcome existing restrictions in the design of plastic mouldings and to utilise new design options. Compact and efficient Because the hot runner gets by without separate diverting ele- ments, very small nozzle gaps can be achieved. Depending on the chosen nozzle size, cavity-to-cavity distances (pitch) from 18 mm can be deployed. The manifold height can also be made 20-30 mm lower than with conven- tional manifold blocks. As with all other hot runner sys- tems from HASCO hot runner, the Streamrunner® can be adapted in- dividually for the respective appli- cation not only as regards the form and size. If desired, it is also available as a fully wired modular system or as a completely assembled hot half with precisely coordinated control technology. T h r o u g h t h e u s e o f t h e Streamrunner®, injection-moulded parts can be produced cost-effectively. The compact design requires smaller mould sizes and thus smaller in- jection moulding machines for production. In addition, the low mass of the manifold block reduces energy consumption, thus achieving an additional cost saving. Top quality – additively manufactured HASCO keeps a close watch on the rapid developments being made in the field of additive manu - facturing and constantly updates the manufacture of the Streamrunner® to take the latest innovations into account. New developments are tested in-house in the company’s technical centre and constantly opti- mised. HASCO hot runner guarantees the highest quality standards to ISO 9001.
